This version of PAC-MAN was released to commemorate the 30th anniversary of the first game, in a partnership between Google and Bandai Namco. It was featured in Google's first page in May 21 and 22, 2010, but it is still playable in the game's its own page. Both Pac-man and Ms. Pac-man are playable (the latter appears by inserting another coin). The game was developed by Google's Marcin Wichary and Ryan Germick.
